Quiz TV Show Joke

A host has a gimmick on his tv show in which he phones people at home and gives them a contest quiz. The other day he got a woman in Ohio who just wouldn't believe that he was talking to her while actually on the air. "I'm on the air, all right," said the host. "Just go into your living room, turn on the set and I'll wave to you." "Oh, I couldn't do that," said the lady. "I'm not dressed."
